More about vanishing PDF on Adobe blogs
Still thinking about the CS5 information and the apparent lack of interest in PDF. I have checked out the MARS blog, nothing recent and also Inside PDF , updated last October.
I still think there is not much going on. The potential for disruption in the next few months is significant. If the CS5 launch is all about Flash then the flat pages of hard copy as at IPEX will have a struggle for attention. Apple definitely will not be there. Adobe possibly mostly on other stands.
